<P>PROBLEM TO BE SOLVED: To suitably control engine performance by improving controllability in an engine combustion state, and to perform suitable control reflected with a change with time even if there are generated an individual difference and the change with time in an actuator. <P>SOLUTION: An ECU 20 calculates a command value of a control parameter by using first correlation data in which a correlation between a plurality of combustion parameters and the control parameter are defined. In this case. the plurality of combustion data include time series data being a specified parameter which is changed in a time series accompanied by the generation of combustion in an engine combustion chamber, and also being data at a plurality of time series points which are defined in advance about the specified parameter, and the first correlation data is obtained by defining a correlation between the time series data at each time series point and the control parameter. Then, the ECU 20 sets a target value of the time series data at each time series point, and calculates the command value of the control parameter on the basis of the target value of the time series data at each time series point by using the first correlation data. <P>COPYRIGHT: (C)2013,JPO&INPIT |
